Open a point below for its explanation and revision guidance.
Students should study instrumental forms which facilitate the development and extension of an opening melody such as binary form, ternary, rondo, theme and variations and fantasia.
Within the 1700–1820 instrumental brief, learn how five forms take an opening melody and develop or extend it. Binary form presents two related sections, often repeated, with contrast between them. Ternary form sets a first section, a contrasting middle, then a return of the first. Rondo keeps returning to a principal theme between contrasting episodes. Theme and variations states a melody then reshapes it through changes of rhythm, harmony, texture, ornamentation or mode. Fantasia is freer, using improvisatory gestures and looser structure to extend ideas. For each form, identify how the opening melodic idea is stated, altered and extended, and be ready to match a described structure to its form.
They should practise harmonising and developing given melodies using the techniques of repetition, variation, extension and motivic working to sustain a piece with a varied and creative musical outcome.
This criterion asks you to rehearse two linked skills on short given melodies: harmonising them (choosing chords that fit the melody and support its phrasing) and developing them so the material sustains a whole piece. Development here means working the melody through repetition (restating it recognisably), variation (altering rhythm, pitch, texture or instrumentation while keeping identity), extension (adding new material that grows from the melody, such as a longer phrase or a new section) and motivic working (taking a short cell and transposing, inverting, fragmenting or sequencing it). A varied and creative outcome means the piece does not simply loop the same tune; contrast and growth are audible. Practise on several given melodies so the techniques become habits rather than one-off tricks.
Students will be required to develop a given melodic phrase into a piece for one instrument and accompaniment.
This row tells you the shape of the Brief 1 composing task: you receive a melodic phrase and must develop it into a complete piece scored for one instrument with accompaniment. Read it as a planning instruction. First, study the given phrase: its key, metre, range, phrase structure and character. Then decide the solo instrument and the accompaniment (for example piano), keeping the writing idiomatic for both. Plan how the phrase will be developed across the piece using repetition, variation, extension and motivic working, and how the accompaniment supports harmony and texture. The period focus of Brief 1 is instrumental music 1700–1820, so let stylistic awareness of that era inform your choices without pasticheing a named composer. Check the final score is complete, legible and playable.
Your focus
- Identify binary, ternary, rondo, theme and variations and fantasia forms from descriptions of their structure.
- Explain how each form develops or extends an opening melody.
- Select an appropriate form when composing within the 1700–1820 instrumental brief.
Show all 9 objectives
- Select chords that fit a given melody and support its phrasing.
- Apply repetition, variation, extension and motivic working to a given melody.
- Produce a piece that sustains the melody with audible variety and creative development.
- Analyse a given melodic phrase for key, metre, range and structure.
- Plan and write a piece for one instrument and accompaniment that develops the phrase.
- Produce a complete, legible and playable score suited to the Brief 1 context.

Marking Points
- Binary form: two sections, typically with contrast and often repeated, extending an opening idea through a second related section.
- Ternary form: statement, contrasting middle section, then return of the opening material.
- Rondo: a recurring principal theme alternating with contrasting episodes.
- Theme and variations: an opening melody restated with changes in rhythm, harmony, texture, ornamentation or mode.
- Fantasia: a freer, improvisatory structure used to develop and extend melodic ideas.
- Explains harmonising as choosing chords that fit the given melody's pitches and support its phrase structure.
- Distinguishes repetition (recognisable restatement) from variation (altered rhythm, pitch, texture or instrumentation that keeps the melody's identity).
- Describes extension as adding new material grown from the melody, such as a lengthened phrase or a new contrasting section.
- Explains motivic working as developing a short cell through devices such as transposition, inversion, fragmentation or sequencing.
- Recognises that a varied and creative outcome requires audible contrast and growth across the piece, not continuous looping of the original tune.
- Applies the techniques to a specific given melody rather than describing them only in the abstract.
Examiner Tips
- 💡When a question describes a structure, name the form first, then justify it by referring to the sections and any return of the opening melody.
- 💡Learn one short example of each form so you can describe how the opening melody is developed or extended.
- 💡Use precise vocabulary — statement, episode, return, variation — rather than vague words like 'part' or 'bit'.
- 💡Name the technique you are using and point to the exact bar or phrase where it happens.
- 💡Check each chord against the melody note sounding at that point before committing to it.
- 💡Plan contrast deliberately: decide where repetition returns and where variation or extension takes over.
- 💡Test the outcome by listening: can you still hear the original melody's identity inside the development?
- 💡Annotate the given phrase first: mark its key, metre, phrase lengths and any motif worth developing.
- 💡Sketch a short plan showing where repetition, variation, extension and motivic working will occur before writing the full score.
- 💡Check playability and notation at the end: clefs, key signatures, dynamics and articulation should all be present and consistent.
- 💡Keep the 1700–1820 instrumental context in mind when choosing textures and accompaniment patterns.
Common Mistakes
- Confusing binary and ternary form: correction — binary has two sections, ternary has a statement, contrast and return.
- Describing rondo as through-composed with no returns: correction — rondo is defined by its recurring principal theme.
- Treating theme and variations as mere repetition: correction — each variation must alter the melody in a recognisable way.
- Assuming fantasia follows a strict repeating pattern: correction — fantasia is comparatively free and improvisatory.
- Treating repetition and variation as the same thing: repetition restates the melody recognisably, whereas variation changes rhythm, pitch, texture or instrumentation while preserving identity.
- Assuming harmonising means adding any chords: the chords must fit the melody's pitches and support its phrasing.
- Confusing extension with motivic working: extension adds new material grown from the melody, while motivic working develops a short cell through devices such as transposition or fragmentation.
- Believing a varied outcome means constant change: contrast must be balanced with recognisable return so the piece coheres.
- Treating the given phrase as a finished piece: it is raw material to be developed, not copied out unchanged.
- Writing for an unspecified ensemble: the task requires one instrument plus accompaniment, so keep the scoring clear and idiomatic.
- Ignoring the phrase's key, metre and range: development should grow from these features rather than contradict them.
- Leaving the accompaniment as block chords only: it should support harmony, texture and the solo line's phrasing.
